SQL Server low performance after Replistor installation

Hi all,

I have one Server with Wk2003 Standard edition SP1.
This Server runs a SQL Server2005 application that uses about 50% CPU process.
I execute some SQL query and take answer in 10 sec
when I just install a RepliStor 6.1, without create specification I have a low performance at SQL application. When a execute same SQL query a take answer in 30 sec.
I stop Replistor services but I keep with problem.
Being necessary remove(uninstall) Replistor application to back normally operation from server.



Thank all suggestion

Replistor reserves an area of memory called the kernel cache for catching all file system changes - the amount of memory requires some configuration to set correctly (see manual - the procedure is in there) - by default it is 5% of physical memory but this can be changed. You need to bear in mind that this memory is reserved so is no longer available to your applications.

It could also be that replication may be causing some contention for disk resources if the kernel cache is inadequately sized and is overflowing to disk. I would suggest firstly ensuring the kernel cache has been sized correctly,
